26 Romain Grosjean finished the GP2 Asia season in style, taking pole position and a win in the feature race in Dubai, to cement his position as series champion. However, ss the series returned to the track on which the Frenchman had scored an incredible double win on his GP2 debut in the opening round of the season, Grosjean found he had far tougher opposition to deal with. After setting a blistering pace for yet another pole position, the Frenchman was beaten off the line by iSport’s Bruno Senna who made short work of pulling out a lead. After a disappointing Asia series, the Brazilian still stood an outside shot at second position in the championship, and blasted off down the road and into what appeared to be an unassailable 17 second lead. Then the pitstops… Senna came in and, having originally decided on a change of two rears, changed his mind on his in-lap as the wear on his left tyres had been unusually high. In the confusion the iSport team changed just one tyre, his left-rear, as they had no front left on hand to change. This silly situation meant Senna had to come in for a second stop as GP2 regulations dictate that at least two tyres must be changed. He fought back to miss eighth position and pole for the second race by mere tenths of a second. But his racecraft was to no avail anyway. The regulations had been broken and Senna was excluded. All that left Grosejan to fly home for an easy win, his fourth of the year, with Sebastien Buemi second and his Arden team-mate Yelmer Buurman third for his first ever GP2 podium. Race Two was just as much fun as the first two laps saw three leaders, as pole-sitter Pavlovic pulled off with a failed engine, before Marco Bonanomi blasted past Jerome d’Ambrosio on lap two for a lead he would keep to the flag. Despite his lead being cut by a Safety Car period, second placed man Buemi never got seriously close enough to challenge for glory. And so Bonanomi took the chequered flag for his first GP2 win, ahead of Buemi and d’Ambrosio. The result meant that Buemi took second in the championship ahead of Vitaly Petrov, with Fairuz Fauzy eventually placing fourth ahead of Senna and Kobayashi. But top of the pile, and the The Asian GP2 series finale confirmed Romain Grosjean as champion, but Bruno Senna's bid for the runner-up spot ended with a farcical tyre stop.
